From Straw Poll to Opinion Poll
Modern opinion polling has been with us since the late 1930s and is now used around the world to help forecast elections and to do market research.
Today, we can鈥檛 imagine an election without an opinion poll gauging public opinion on who鈥檚 leading, who鈥檚 won a debate or who鈥檚 more popular with a specific group of voters. Even our favourite chocolate bars and footballers are subject to a poll. But how did straw polls evolve into the scientific number crunching we know now? What is their purpose and impact? How differently are they used around the world? And just how reliable are they?
